8 Claims.

tight closure when desired; may readily be opened when desired and which will include a cap that will be permanently connected to the container.

These and other .features, capabilities and advantages of the invention will appear from the subjoined detail description of one specific embodiment thereof illustrated in the accompanying drawing in which:

Figure 1 is a fragmental perspective of a container equipped with a valve made according" to the present invention in open position;

Fig. 2 is a fragmental perspective similar to Fig. l but showing the valve in closed position;

Fig. 3 is a fragmental elevation showing the valve in section on the line 3--3 of Fig. 2;

Fig. 4 is a fragmental elevation showing the valve in section on the line 4-4 of Fig. 1;

Fig. 5 is a fragmental perspective showing the container with the cap removed;

Fig. 6 is a fragmental perspective of the cap removed; and

Fig. 7 is a section on the line 'l-'l of Fig. 3.

In the embodiment illustrated, there is shown a tubular container l preferably composed of some suitable moldable metal having a diminished neck 2 formed into a valve seat, see particularly Fig. 5, with an enlarged thickened portion 3 extending inclined to the axis of the neck 2. The exterior of the portion 3 is provided with a screw thread 4 and the inclined face is provided with a spiral valve seat 5 which is sub stantially perpendicular to the axis of the spiral terminating in a shoulder or abutment 6. Outwardly of the shoulder 6 there is formed a short offset or recess 1. Extending parallel with the axis of the neck 2 and preferably along the shortest wall portion thereof, there is provided an abutment or stop 8.

To cooperate with the valve seat thus formed at the end of the neck 2, there is provided the cap 9 preferably composed of metal having an internal thread ID to receive the thread 4 of the neck 2. The cap preferably has a small finger engaging tab II or the like for turning the same. The cap 9 is disc-shaped having a portion cut away at I2 with one side inclined as indicated at l3.

The cap 9 is preferably filled with some suitable yieldable material such as cork I 4 or the like which is formed or cut to present a spiral valve face l5 to cooperate with a slide on the valve face 5. The cork I4 is recessed at Hi. The 5' cap 9 in addition is provided with a projection I'l extending down from the lower end thereof to cooperate with the stop 8. The projection I! will not be formed until after the cap has been secured to the neck 2 when the projection 10 ill will cooperate with the stop 8 to anchor the cap against displacement or in permanent association with the neck 2.

When the cap 9 is mounted in place as indicated in Figs. 1 to l inclusive, it will be seen that (see Fig. 2) the recess 7 Will receive the shoulder I 6 of the spiral face N3 of the cork l4 when the cap is in closed position and that the edge of the metal portion of the cap will extend to and beyond the outer face of the spiral 4 on the neck, and that in turn when the cap is in open position, that shown in Fig. 1, the shoulders 6 and IE will be spaced from one another and that the opening to the interior of the neck 2 will be provided according to the space formed 5 between the shoulders 6 and I6.

It will also appear that the spiral faces 5 and IE will cooperate with one another to form a Wedging closure effectively to seal the contents of the container when the cap is turned into the position indicated in Fig. 2. In this closed position, it will appear that the shoulder 6 will act to overlap the abutment between the shoulders I and I6.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.

I claim: 40

1. In a discharge control valve, the combination with an outlet forming tubular body having the tubular edge of its free end formed into a single convolution spiral seat, the face of the spiral seat substantially perpendicular to the axis of the spiral, and an external thread formed adjacent said tubular edge, of a cap having a yieldable disc cut to conform to said spiral seat, and an internal thread cut on said cap to engage said external thread.

2. In a discharge control valve, the combination with an outlet forming tubular body having the tubular edge of its free end formed into a single convolution spiral seat, the face of the spiral seat substantially perpendicular to the axis of the of a cap having a disc cut to conform to said spiral seat, an internal thread cut on said cap to engage said external thread, and a projection adjacent to said internal thread to engage and cooperate with said external thread permanently to anchor said cap to said tubular body.

3, In a discharge control Valve,,the combination with an outlet forming tubular body having the tubular edge of its free end formed into a single convolution spiral seat with a shoulder formed between the ends of the spiral convolution, an external thread formed adjacent said tubular edge, and a flange on said body extending beyond said shoulder, of a cap having a spiral face cut to conform to said spiral'seat with a shoulder formed between the ends of the spiral convolution, an internal thread cut on said cap to engage saidexternal thread, said flange overlapping the meetingplace of said shoulders when said cap is in closed position.

4. In a discharge control valve, the combination with an outlet forming tubular body having the tubular edge of its free end formed into a'single convolution spiral seat, and an external thread formed adjacent said tubular edge, of a cap having' a spiral face out to conform to said spiral seat, an internal thread 'cut on said cap to engage said external thread, and a finger engaging tab extending from the outer edge of said cap to facilitate manipulating the same.

5. In a discharge control valve, the combination with an outlet forming tubular body having the tubular edge of its free end formed into a single convolution spiral seat and a screw thread formed adjacent said tubular edge, of a cap having a spiral face cut to conform to said spiral seat, a second screw thread cut on said cap to engage said first screw thread, and means formed on said cap to facilitate manipulating the same.

6. In a discharge control valve, the combination with an outlet forming tubular body having the tubular edge of its free end formed into a spiral seat and a screw thread formed adjacent said spiral seat, of a cap having a spiral face conforming to said spiral seat, and a second screw thread formed on said cap to engage said first thread.

7. In a discharge control valve, the combination with an outlet forming tubular body having the tubular edge of its free end formed into a spiral seat and a screw thread formed adjacent said spiral seat, of a cap having a spiral face conforming to said spiral seat, a second screw thread formed on said cap to engage said first thread, and a yieldable substance interposed between said spiral face and spiral seat.

8. In a discharge control valve, the combination with an outlet forming tubular body having the tubular edge of its free end formed into a spiral seat and a screw thread formed adjacent said spiral seat, of a cap having a spiral face conforming to said spiral seat, a second screw thread formed on said cap to engage said first thread, and opposing stops on said tubular body and cap to cooperate with one another permanently to anchor said cap to said tubular body.
